avr32: add support for EarthLCD Favr-32 board 



This patch adds support for the Favr-32 board made by EarthLCD.

This kit, which is also called ezLCD-101, has a 10.4" touch screen LCD panel,
16 MB 32-bit SDRAM, 8 MB parallel flash, Ethernet, audio out, USB device,
SD-card slot, USART and various other connectors for cennecting stuff to SPI,
I2C, GPIO, etc.

	help

	  Specify the target rate the internal DAC should try to match. This

	  will use PLL1 to generate a frequency as close as possible to this

	  rate.



	  Must be within the range 32000 to 50000, which should be suitable to

	  generate most other frequencies in power of 2 steps.



	  Ex:

		48000 will also suit 24000 and 12000

		44100 will also suit 22050 and 11025

		32000 will also suit 16000 and 8000
